Beekeeping is an ancient DIY art, performed by amateurs and makers for
centuries.
Anyone can produce natural honey at home. People keep bees in
many different kinds of hives, but we will focus on a cheap and simple
design, called the Honey Cow.
The Honey Cow is designed to mimic nature as much as possible. Unlike
commercial hives, it does not have frames, foundation or excluders.
Instead, it just has top bars, allowing the bees to do what they would
in a fallen log: build beautiful, natural combs. Because it is less
intrusive to the bees, it's easier to make and manage, which makes it a
perfect beginners backyard hive.
Once you have a hive, you will want to gather a few extra bits of
equipment, like a veil, a smoker, and a bee feeder. With your equipment
at hand, you can explore ways to get your bees, from capturing a swarm
to buying a package or nucleus from a fellow beekeeper. After your bees
have had a full summer to build up honey, you can start reaping the
rewards of tending bees: wonderful, home-grown honey.
I encourage everyone interested in beekeeping to join a local bee club.
These clubs are filled with wonderful people who love to help get
beginners started. Don't be discouraged if folks in your bee club don't
have the same type of hive as you. There are as many ways to keep bees
as there are beekeepers.
